Milwaukee 1/4" Impact Torsion Bit Set 40 pcs for Phillips, Pozidriv, TORX®, Hex – drive size 1/4"

The Milwaukee 1/4" Impact Torsion Bit Set 40 pcs is a comprehensive assortment of impact-rated bits and accessories designed for use with 1/4" hex-drive impact drivers. The set covers Phillips, Pozidriv, TORX® and hex head screw profiles and includes impact torsion bits that absorb torque peaks to reduce tip breakage and extend service life. Components are made from high-performance alloy steel with a manganese phosphate finish and are supplied in a robust glass-fibre reinforced case with a lock-in system for secure storage and easy transport.

Advantages

The torsion zone design reduces stress concentration on the tip, improving resistance to sudden impacts and increasing the working life of each bit. Color-coded sleeves on the TORX® bits speed tip identification on site, while the magnetic quick-release bit holder and magnetic nut drivers simplify fast changes and reliable retention during high-torque operations. The durable case features a 180° locking mechanism, split-able lid and body and swiveling racks that optimise storage and accessibility.

Suitable for

• Construction and carpentry fastening with impact drivers
• Mechanical assembly and maintenance work requiring impact-rated bits
• Electrical and HVAC installations that use Phillips, Pozidriv or TORX® fasteners
• Workshop and mobile toolkits where durable, organised storage is needed

When it may not be suitable

This set is intended for use with impact drivers and high-torque applications; it is not optimised for precision hand-screwdriver tasks where fine torque control is required. For applications requiring non-magnetic bits, specialty tamper-proof security profiles, or sizes outside the Phillips, Pozidriv, TORX® and standard hex range, a different or supplementary bit set may be necessary.

Key specifications

• Contents: 40 pieces including impact bits, magnetic quick-release bit holder, magnetic nut drivers and hex drive socket adaptor
• Drive size: 1/4" hex drive (compatible with 6.3 mm style holders)
• Bit material: high-performance alloy steel with manganese phosphate finish
• Bit length: standard 75 mm magnetic quick-release bit holder included
• Torsion zone: integrated into impact bits to absorb torque peaks
• Case: glass fibre reinforced plastic with 180° locking feature and swiveling racks

How to use

Select the correct bit profile and size for the fastener, insert the bit into the magnetic quick-release holder or directly into the impact driver chuck, and engage the driver at the appropriate torque/speed for the material. The torsion zone is designed to flex under torque peaks; normal operation requires no special handling beyond standard impact-driver safety and fastening practice. Use the magnetic nut drivers and socket adaptor where applicable for hex-head fasteners and store bits in the provided case after use to protect tips and maintain organisation.

What to consider before purchase

• Verify compatibility of the 1/4" hex drive with your impact driver and bit holder system
• Confirm the included bit types and sizes match the screw profiles used in your work
• Consider whether non-standard security or very fine precision bits are required for your tasks
• Assess whether the physical size and layout of the case suit your storage or toolbox configuration

Usage recommendations

Use with a properly rated impact driver, match bit profile to fastener to avoid cam-out, and replace worn tips to maintain fastening quality. Keep bits clean and stored in the provided case to prolong service life and identify sizes quickly using the colour-coded TORX® sleeves.
